Under which circumstance will a disease not spread beyond a few individuals in a population? If the rate of infection is lower than the rate of recovery, the reproductive ratio of the infection will be less than 1. If the rate of recovery is lower than the rate of infection, the reproductive ratio will be greater than 1. If the primary case infects a large number of people very quickly, the reproductive ratio will be less than 1. If the reproductive ratio is greater than 1, only a few individuals in a population will be infected.

Answers

Answer:

The correct answer is - If the rate of infection is lower than the rate of recovery, the reproductive ration of the infection will be less than 1.

Explanation:

The rate of infection is the chances or occurence of new cases of infection in a particular population over a particular time period and the rate of recovery is the occurence of the recovery of an individual case over a period of time. These two rates determines if a disease or infection is spreading faster or lesser.

The higher the rate of infection to rate of recovery it is more lkely to be spreading rapidally and higher the rate of recovery the infection not spreading beyond few individuals in the population. In the later case, the reproductive ration of the infection will be less than 1.

list few points on the importance of sun in power supply.​

Answers

Answer:

The sun provides more than enough energy to meet the whole world's energy needs, and unlike fossil fuels, it won't run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity in an efficient and cost-effective way.

Answer:

Nothing is more important to us on Earth than the Sun. Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.


Question 10 of 10
Which organisms convert nitrogen gas into a form that is usable by plants?
A. Fungi
B. Algae
C. Bacteria
D. Animals

Answers

Answer:

bacteria

Explanation:

Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.

Neurospora is an ideal organism to study the effects of genetic mutations because of several reasons. What is one of these

Answers

Answer:

Due simple growth.

Explanation:

Neurospora is an ideal organism to study the effects of genetic mutations because it is easier to growth and are simple. Neurospora crassa is used as a model organism because it has a haploid life cycle and easier to grow that makes genetic analysis simple. Analysis of genetic recombination is facilitated by the ordered arrangement of the products of meiosis in Neurospora ascospores so due to simple growth and haploid life cycle we can considered   Neurospora is an ideal organism.

What conclusion can be drawn concerning an inhibitor if the Km is the same in the presence and absence of the inhibitor

Answers

Answer: The inhibitor has a structure that is not similar to the substrate.

Explanation:

Enzymes are molecules that act as catalysts of chemical reactions, accelerating the reaction rate without affecting the equilibrium of the reaction, as long as it is energetically possible. They act on molecules called substrates, which are converted into different molecules called products.  

Enzymes are very selective with their substrates and are also susceptible to inhibitors which are molecules that regulate enzyme activity, inhibiting its activity. Inhibitors can be classified as reversible and irreversible. Irreversible inhibitors bind covalently to the enzyme with no possibility of reversing the modification they make, while reversible inhibitors bind reversibly to the enzyme and can reverse the modification.

A reaction occurring under the control of an enzyme reaches equilibrium much faster than the corresponding uncatalyzed reaction. The reaction, i.e. the production of products, can reach a saturation point if the substrate concentration increases too much, decreasing the concentration of free enzyme, which becomes the form with bound substrate. At the maximum rate (Vmax) of the enzyme, all active sites of the enzyme have substrate bound, and the amount of complexes is equal to the total amount of enzyme. The amount of substrate required to obtain a given reaction rate is also important and this parameter is given by the Michaelis-Menten constant (Km), which is the concentration of substrate required for an enzyme to reach half its maximum velocity. Each enzyme has a characteristic Km value for a given substrate, which can tell us how close the binding between the substrate and the enzyme is. Then, inhibitors bind to the substrate and increase the Km value as it interferes with the binding between substrate and enzyme. In this case, the Km value of the enzyme is the same in the presence and absence of the inhibitor, this means that there is no change, because the inhibitor has a different structure to the substrate, it does not bind and does not change the Km value.

In intramembranous ossification, newly formed bone that is immature and not well organized is called ______.

Explanation:

In intramembranous ossification, newly formed bone that is immature and not well organized is called woven bone. Osteoblasts are the type of cells that is responsible for the formation of new bone.

Why do only certain cells respond to particular signaling molecules that are sent throughout the body

Answers

Answer:

The presence of appropriate receptor dictates which cells will be receptive to a particular signal.

Explanation:

Some cells only respond to certain molecules because they have receptors to accept those molecules. Hence, due to this, only some molecules can be accepted by the cells.

How does a particular cell accept the molecules?

Hormones are secreted by endocrine glands into the blood. The endocrine glands, such as the pituitary gland, secrete their hormones directly into the blood, but not all cells of the body can bind to the molecule and perform the cellular functions.

The cells' surface has receptors for molecules such as peptide molecules or polar hormones that can't directly enter the cell. Hence, they bind to the cell surface receptors and send signals with respect to those hormones.

A hydrophobic hormone can directly enter the cell as it can easily pass the plasma membrane. After entering the cell, it has some receptors in the nucleus or in the cytoplasm. This hormone can perform functions such as gene activation after binding with them.

Hence, after binding with receptors, they show their performance, and not every cell has the same receptors for a single molecule.

It is impossible for sperm to be functional (able to fertilize the egg) until after ________. Group of answer choices

Answers

Answer:

The answer is "they undergo capacitation"

Explanation:

Sperm migrate through uterine contractions and the energies of its flagella to the uterine tube. In sperm motility, reverse peristalsis is engaged in the uterus and uterine tubes. For a sperm cell to fertilize an egg, it takes approximately 24 hours. The surface of the egg changes as the sperm penetrates the egg, therefore no sperm is allowed within. The kid is fully genetic, including whether it's a boy or a girl at the time of fertilization. Until they are trained it is difficult for sperm to be working.
